electical issues
 

hello out there.i am new to the site but not new to 4runnners. i have my third 4runner and like the trucks very much.
having said that i have a problem i could use some help with. my 1996 3.4 4runner sometimes turns itself to the on position with no key in it.
in this situation the drl lights come on,abs pump powers and a couple of dash lights come on.the only one that is consistent is the oil pressure light.
i dont think it is the ignition switch and i am looking at the integration relay but can find no wiring diagram on the box.any help would be appreciated.
thanks
